They are best known for killing two members of notorious criminal Bill Doolin’s outlaw gang the “Wild Bunch” and collecting the $5,000 bounty for each. The oldest of the Dunn brothers, Bill, also aided Deputy U.S. Marshall Heck Thomas in tracking and putting down Bill Doolin himself, ending the Wild Bunch once and for all. In the early 1860s, he became a bounty hunter after singlehandedly putting an end to the reign of terror brought on by the notorious Mexican outlaws, Felipe and Julian Espinosa, whose heads he brought back in a sack. He never collected the whole reward of $2,500 for the job, but he did go on to bring in a number of other Mexican and Native American outlaws in the years following. Gardner raided a number of speakeasies and moonshine sills and set a record for the thousands of gallons of illegal alcohol he confiscated and poured out. A medical issue required him to retire from bounty hunting in 1927, but the legends of the Dry Wolf continued to live on for some time after his retirement. The event had a notable effect on the wrestler’s career and he eventually left it behind to pursue a new line of business—bounty hunting. Schultz’s time as a bail recovery agent took him as far as Puerto Rico and even Egypt, and by the time of his retirement he had made over 1,700 arrests and worked closely with both the FBI and DEA. His most infamous and well-known dealings, however, was when he spent a number of years as a scalp hunter for the Mexican government, charged with hunting down, killing, and scalping Apache raiders in Mexico, as well as taking women and children prisoners. He excelled at this. At one point, he became so successful that the nearly bankrupt government branded him a traitor and forced him to flee the country because they could not afford to pay him for his work. Kid had a $500 bounty on his head for anyone who could capture him. Pat followed his old friend the Kid for some time, even managing to capture him at one point, before finally confronting him him in 1881 and shooting him through the chest. Although many viewed Pat as a hero, he never received his bounty money as it specified that the Kid be captured alive. Much of the community vilified him for ambushing the Kid in what was seen as an “unfair killing,” and as a result Garrett would lose his re-election as sheriff and eventually move to Texas. Her job is all digital. Searching the web for the digital signatures, social media presence, and criminal financial records, she tracks it all with a computer, making her able to find targets that nobody else can.

His cases took him across the Western United States, as far north as Alaska, and as far south as Mexico City, chasing robbers and outlaw gangs. At one point he even infiltrated Butch Cassidy’s notorious Train Robbers Syndicate using a pseudonym and fake identity. Over time, Siringo came to be known as the “Cowboy Detective,” a name owned when he wrote his own biography using the aforementioned nickname as the title. He disguised himself, snuck into William’s congregation, and fired two shots into the prince’s back. Gérard ran, hoping to leap into the moat, but guards captured before he could make it. Four days later, his captors brutally executed him by being quartered, disemboweled alive, and beheaded. Despite his death, King Philip honored his promise and rewarded Gérard’s surviving family with three country estates and noble titles. Mickey would eventually go on to become a successful bounty hunter, bagging a number of high-bounty criminals. At one point, he trailed the notorious Apache Kid, who had a reward of $15,000 on his head at the time. Whether or not Mickey successfully caught him, however, depends on who you ask. He caught more than 12,000 fugitives over the course of his 40+ year career. Surprisingly, he also opened his own home to many of the criminals he brought in, finding them jobs as well as offering them financial support or counseling. Sadly, he was killed in a car bombing in 1994. His bounty hunting business as well as his desire to rehabilitate delinquents lived on under the watch of his wife Dottie and daughter Brandi. As a priest hunter, Mullowney had even fewer morals than in his lawbreaking days, reportedly turning in a estimated 2,000 priests using underhanded techniques such as manipulating his family, or pretending to be deathly ill and calling for a priest to confess his sins to, only to pull out a hidden knife and kill his confessor.

Duncan tracked the fugitive all the way to Florida before finally catching him and serving justice once and for all.
